Most Heroic Moments in Comics

When Thor and Hyperion made one final stand against The Beyonders.

The Time Captain America fought Thanos.His last stand.

I can't remember the exact comic issue I want to say it was During the Siege of Asgard event (I'm probably hella wrong) where Odin was being his normal, selfish, arrogant self, and refused to help stop some threat (can't remember what) that would cost much devastation, and Captain America walks up to him and basically tells Odin off, little Steve Rodgers walked up to the king of Asgard, Odin and called him out to his face, that's pretty ballsy and heroic in my opinion.

Batman defeats Hulk.
